@uiten tates 'gatent' @Hina l y .Linus woonwoHirn, or TROY, PENNSYLVANIA@ Letters Patent No. 78,169, dated May 19, 1868.

'http rgettle referenti im ttm tttfs taunt mit mating niet uf tige tama TO ALL WHOM 1T MAY CONCERN: p Be it known that I, LINSWOODWORTH, of Troy, in the county of Bradford, and State' of Pennsylvania, have invented a new and useful Improvement in' Hay-Elevators; and do hereby declare that the following is a full, clear, and `exact description of the same, reference being had to the accompanying drawings, Amaking a portion of this specification, in whichl v l Figure 1 is a side view of a hay-elevator made according to my invention.

Figure 2 is a side view of the same, taken atright angles` to iig. 1.

Similar letters of reference indicate corresponding parts in both iigures.

This invention consists in' two bows pivoted together, and having their Aextremities made pointed, and furnished with lateral spurs,'so combined with a toggle-bar, slide-bar, and snpportingshank, that a very simple and etiicient apparatus for pitching or elevating hay and like material by horse or other suitable power is secured.

To enable others to understand the construction and operationof my invention, I will proceed to describe it with reference to thedrawings. I i

A and B indicate two bows, the general configuration of whichV is shown more fully in iig.- 1, and which may be formed from Hat metal hars. VVOne Qi`,these bows is placed within: the other, and -the two arepivoted together by transverse pivots, The end portionsof each of the bows are enlarged, and are made pointed, as shown at a', each of the end'portions being furthermore formed with a spur or shoulder, b, the shouldersl upon one bow extending in a directioniopposite to that of those upon the other.A Secured to the upper or middle portion 0f the Ainnermost bow is a plate or shank, C, which extends past the adjacent part of the other or outer bow, and is furnished with straps or guides, d, thronghlwhich a 'slide-bar, D, has a. longitudinal movement. The lower end of the slide-barD has hinged or pivoted to it onel endof a toggle-ban'E, the opposite end of which is pivoted in a similar 'manner to the edgeot' theouter bow, as shown at b. Attached to the upper end of the slide-bar D isa tripping-cord, F, which passes through a hole, c, in the upper end of the shank C, and over a. friction-pulley, e', provided at the lower part of such hole. u

The two bows being placed in `a position parallel with each other, so that the sloping back a* of each end portion ot' onel bow will be situated across the shoulder l) of the other, as indicated more fully in iig. 2, the pointed ends of thebows may bethrust down into the mass of Ithe hay, or like material to be elevatedor pitched to any requisite depth, which being done, the slide-bar D is forced downward,.and, acting through the togglebar E, forces apart the upper'ends of the two bows, thusspreading apart the lower portions thereof, as repre sented in blue outline in iig. 2, so that the spurs or shoulders b, being thrust laterally outward, catch in and under the hayor material, to retain the saine upon the apparatus while the latter is raised to the required -extent by horse or other' powexgapplied in the-usual or any suitable manner to the draught-rope, attached to the upper end of the shank C, and' shown in red outline in g. 1. When the hay is .thus elevated to the requisite height, the tripping-cord F is pulled, and, drawing upward the-slide-bar D, brings the two bows lto their original` parallel position, thus withdrawing the spurs or shoulders from the hay or material, and discharging the same from the apparatus. V

What I claim as my invention, and desire to secure by Letters Patent, is

The two hows, pivoted together, and having theirextremit-ies pointed, and furnished with lateral spurs or Bl1011lders,in combination with the toggle-bar, slide-bar, and shank, substantially as and for the purpose specified.
